<div>When ever we do a roll out of Asterisk in a small business environment
replacing an old key system or legacy PBX the receptionist always asks us,
"How do I know if someone is on a call before transferring them?". My typical
answer is "why do you need to know, just do an attended transfer and if they
can take the call they will, if they can't just tell the caller the person is
busy". If the receptionist insists on "knowing" we give them FOP.<br><br>Has
anyone out there devised a better way to let a receptionist "know if someone
is on a call"?</div></blockquote></span></div><div></div>
